如何使用Tomcat启用静态内容（images，css，js）的浏览器缓存？

Question

How to enable browser caching of static content(images, css, js) with Tomcat? Preferable solution will be editingspring MVC config files or web.xml

Answer 1

try (with changing the values)

<mvc:resources mapping="/static/**" location="/public-resources/" 
       cache-period="31556926"/>
<mvc:annotation-driven/>

You can also use an interceptor:

<mvc:interceptors>
   <mvc:interceptor>
    <mvc:mapping path="/static/*"/>
    <bean id="webContentInterceptor" 
         class="org.springframework.web.servlet.mvc.WebContentInterceptor">
        <property name="cacheSeconds" value="31556926"/>
        <property name="useExpiresHeader" value="true"/>
        <property name="useCacheControlHeader" value="true"/>
        <property name="useCacheControlNoStore" value="true"/>
    </bean>
   </mvc:interceptor>
</mvc:interceptors>

See the MVC docs

Answer 2

If Spring 3.0 is being used, <mvc:resources> is one way to implement caching of static resources. This link has some documentation.

Answer 3

For those who use Java configuration, you can manage caching parameters using ResourceHandlerRegistry , there is example how do I set up different caching preferences for different content types:

@Configuration
@EnableWebMvc
// ...
public class WebConfiguration extends WebMvcConfigurerAdapter {

    // ...

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {

        registry.addResourceHandler("/ui/css/**")
                .addResourceLocations("classpath:/WEB-INF/css/")
                .setCacheControl(CacheControl.maxAge(1, TimeUnit.DAYS));

        registry.addResourceHandler("/ui/js/**")
                .addResourceLocations("classpath:/WEB-INF/js/")
                .setCacheControl(CacheControl.maxAge(1, TimeUnit.DAYS));

        registry.addResourceHandler("/ui/**")
                .addResourceLocations("classpath:/WEB-INF/")
                .setCacheControl(CacheControl.noCache());
    }

    // ...
}
